y - 3 = -2(x+4)
we will first rearrange the equation to be in the form; y=mx+ b
where m is the slope and b is the intercept
y -3 = -2x - 8
add 3 to both-side of the equation
y = -2x - 8 +3
y = -2x -5
comparing the above with;
y=mx + b
slope m = -2 and Intercept b = -5
Hence; the line has a slope of -2 and a y- intercept of -5
